Transcription

1 Performed By: Date: The following sets of audit questions can be used to validate and verify that the is understood and being properly applied. Any non-compliant issues will be identified and prioritized as corrective actions to ensure that the is being properly and consistently applied. The audit questions are organized into sets of questions based on the prioritized preventive and protective control measures that the outlines as well as Occupational Health & Safety Management System Standards. 1. De-energize is always the first choice; 2. Substitution; 3. Engineering and Equipment Safety by Design. Maintain Critical Electrical Equipment; 4. Increase awareness by the application of signs and the use of barriers; 5. Administrative controls, training and procedures; 6. Electrical Specific PPE, Tools & Equipment, as the last line of defence, and ensure it is appropriately used and maintained. Table 2 identifies items that should be examined during the Internal Electrical Safety Audit. Validation and verification can be completed by Plant/Facility walk-through inspection(s), interviews with the responsible Qualified Electrical Worker(s) or other Worker Roles, and a review of related documentation. Auditing the items listed will provide an indication of the effective implementation of the Electrical Safety Program and related documentation such as supporting policies, practices, safe operating procedures, electrical safe work procedures, related Canadian Electrical Code (CEC) Part 1 compliance and recognized industry best practices. CSA Z462 Workplace electrical safety Standard or NFPA 70E Standard for Electrical Safety in the Workplace are the primary reference Standards. The following Electrical Safety Audit Process should be followed: 1. Schedule when you will complete the Audit, and advise management and workers that it will be completed and that they may have to participate in an interview or in verification/validation of the audit questions. 2. The Electrical Safety Audit will also validate that applicable requirements of the overall Occupational Health & Safety Management System (OHSMS) are in place, and been followed with respect to energized electrical work. Relevant content that should be applied against electrical hazard management is Safe Work Permit, Hazard Assessment, FLHA/FLRA, Preventative and Protective Control Measures (e.g. specific information on Electrical Specific PPE, Tools & Equipment), Incident Reporting & Investigation, Emergency Response, Management of Change, etc.. 3. Retrieve the latest revisions of the Electrical Safety Program, and supporting policies, practices, safe operating procedures, forms, checklists, and electrical safe work procedures. 4. Retrieve and confirm that you have the latest Revision of the Plant/Facility Electrical Single Line Diagram(s) and they are as-built. 5. Execute the Internal Electrical Safety Audit by completing the questions in Table ( ) Page 1 of 20

2 Use of the : This list of questions provides a broad review of the requirements of the Electrical Safety Program. The questions should be reviewed while completing the walk through inspection of the electrical power distribution system(s), during interviews, and when you have retrieved relevant documents. You will also have to inspect all available Electrical Specific PPE, Tools and Equipment (e.g. available for use, stored properly, individually or shared, check in/out system if shared, properly laundering, general condition as found (e.g. not torn, contaminated), valid third party test date (e.g. rubber insulating gloves within the last 6 months, hot sticks within the last 24 months and temporary protective grounds within the last 36 months). When completing inspections, interviews, or reviewing documents or inspecting Electrical Specific PPE, Tools & Equipment the criteria against which you are reviewing the findings can be identified by: You can use the criteria letter when recording results in the Comments/Observation column of Table 1. R C S M Table 1 Comments/Observation Verification/Validation Criteria Description Regulations Codes Standards, CSA Z462, Other Overall Occupational Health & Safety Management System Requirements (e.g. CSA Z1000, ANSI Z10etc.) Generally as the auditor you are looking for the acceptable E Electrical Safety Program application of the prioritized list of preventative and protective B Best Practice control measures with an electrical hazard focus that are included O Other in the Electrical Safety Program: 1. Eliminate the hazard, de-energize is the first choice (e.g. application of LOTO program, Establishing an Electrically Safe Work Condition); 2. Substitution (e.g. use of NGRs, Arc Resistant Switchgear) 3. Reduce the risk by design (e.g. Engineering solutions, equipment solutions, Safety by Design, Engineering Incident Energy Analysis, circuit breaker & relay changes to reduce incident energy, incident energy reduction with Arc Reduction Maintenance Switches (ARMs), incident energy reduction with Arc Flash Relays, IR scanning windows used, etc.); 4. Electrical equipment maintenance (e.g. appropriate PMs in place); 5. Use safer work systems that increase awareness of potential hazards (e.g. apply safeguards like signage, barriers, etc. the Electrical Work Zone is been used with red tape and a tag, proper use of Shock Approach Boundaries and Arc Flash Boundary); 6. Implement administrative controls training and procedures (e.g. review training records, use of Energized Electrical Work Permits, use of Energized Electrical Job Hazard Analysis (EEJHAs), audit status of Electrical Safe Work Procedures/Standard Operating Procedures, etc.); and 7. Use Electrical Specific Personal Protective Equipment (PPE), Tools & Equipment, as a last line of defense, and ensure it is appropriately used and maintained (e.g. available, stored properly, shared check in/out system working, check condition, laundered properly, tested current, etc.). Please also note that the Auditor can add to this list of questions or modify the way the question is asked in an effort to extract the verification/validation data required to make a credible assessment of the status quo.
